Machine Overview
Designed for rotational stone workpieces with varying diameters and radiused transitions, this polisher keeps its heads in contact as the profile changes. Multiple coordinated three-axis head groups, compliant pneumatic pressure control and a series of tapered abrasive rods support consecutive rough, intermediate and fine polishing passes.
Workpieces & Applications
Suitable for ornamental columns, balcony balusters, vase-shaped columns, column bases and rotational stone stool components. Applications include garden stonework and architectural decoration. Suitability depends on the rotational profile, diameter transitions and required radii.
Core Process
- Coordinated three-axis head groups: follow changing diameters and radiused sections of the workpiece.
- Compliant pneumatic pressure control: accommodates blank variation and improves consistency of contact pressure.
- Series of tapered abrasive rods: supports successive rough grinding, intermediate grinding and fine polishing passes.
- Automatic wear compensation: compensates for abrasive wear to reduce repeated manual adjustment.
Key Features
- Profile following: handles changing column diameters and rounded transitions with less repetitive manual finishing.
- Consistent surface quality: combines contour following and pressure control to improve consistency across a batch.
- Connected processing stages: successive polishing passes support batch production planning.
- Operator training: a workpiece-specific process reduces dependence on manual polishing experience.
